Wish that that were the case.
My body would appear to be a particularly attractive source of nutrients for mosquitoes.
In fact, I'm a very good mosquito repellent to keep near you -- they won't bother you one bit if I'm around!
Already this season, I've lost count of the number of bites I've accumulated.
So surely if they sucked fat, rather than blood, I'd not need to worry about my weight at all!
